CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 578,699, dated December 22, 1896.

Application fil d November 7, 1893. Serial No. 490,298. (No model.) Patented in France May 3, 1893, No. 229,817, and in Germany September 1'7, 1893, No. 79,603.

To (all, whom it may CON/0677b:

Be it known that I, HENRY POTTIN, civil engineer, of 43 Rue St. Georges, Paris, in the Republic of France, have invented a new Cash-Register, (for which I have obtained Letters Patent of France for fifteen years, No. 229,817, dated May 3, 1893, and also Letters Patent of Germany, No. 79,603, dated September 17, 1893;) and I do hereby declare that the following is a full and exact description thereof, reference being made to the accom panying drawings.

The object of this invention is to increase the accuracy and insure the satisfactory operation of cash-registering mechanism.

To this end the said invention consists in certain improvements in the totalizer and devices connected therewith, in the construction and combination of the mechanism for exhibiting the indicating devices and returning them to their original position, and in divers details of construction and combination hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents an elevation of the apparatus, taken from the cashiers side, the key-racks being removed and the casiu g being vertically sectioned to show the mechanism within. Fig. 2 represents a plan view of the same, the casing being horizontally sectioned for the same purpose. Figs. 3 and 4 represent two elevations taken at opposite ends of the registering mechanism, the casing being sectioned vertically. Fig. 5 represents an exterior plan view. Figs. 6 to 20 represent detail views of various parts of the mechanism.

A designates the casing, which has an inclined upper front part a, as usual, to serve as a desk for the cashier. This is provided with guide-slots a Fig. 5, for the ordinary sliding keys or pusher-buttons b,which are attached, respectively, to rack-bars 0, arranged in parallel series just under the inclined part a of the casin g. These rack-bars respectively engage and turn the toothed disks f, Figs. 1, 2, 3, 4, and 6, which are mounted loosely in corresponding series on a fixed shaft or rod g. Segments h are attached to and turn with the said disks, respectively, each segment having its outer face divided into ten equal parts,

numbered from 0 to 9 and arranged so that any one of the said numbers may be seen through a window 1', Fig. 5, in the said inclined part a of the casing A. These windows i altern ate in position with the guide-slots a and are equal in number to the same. The cashier on receiving a sum of money slides down the pusher-buttons in their slots and stops each when the right figure appears at its window to indicate the sum received. 011 the said shaft g are also mounted loosely a series of indicating-segments 7;, each of which is connected to one of the said disks by a bent bar or rod Z, the first disk on the left being thus connected to the first segment 7; on the right, the second disk on the left to the second segment on the right, and so on. WV here the bars or rods Z must pass through intervenin g disks, the latter are provided with areshaped slots m, which allow the said disks and bars to move independently about said shaft without obstructive contact. The bar or rod Z, connecting the innermost disk fand segment is, of course does not pass through any disk.

The above system of connection, Figs. 1, 2, 3, and 9, insures the exhibition, by segments in through the window j in the customers side of the casing, of the same figures which simultaneously appear through windows i on the cashiers side, as stated, the corresponding segments h and being similarly graduated.

The disks f are each provided with three sets of teeth 6, 'n, and n, of different size and shape and occupying distinct parts of the periphery. The teeth 6 engage the racks or rack-bars c. The teeth we engage, respectively, gear-wheels 0, arranged in corresponding series, when the latter are shifted into position therefor. The teeth a are used, in connection with a stopping or checking roller, for holding the said disk motionless in each instance, as required. The mechanism for operating the said roller to move it into or out of such locking engagement will be hereinafter described.

All the mechanism is driven by a springdrum H integral with a toothed gear-wheel H, loose on a shaft K, which shaft turns in fixed bearings, one of the ends of the coiled ICO the latter, while the other end is attached to the said. shaft. The said wheel II meshes with an idle'wheel I, loosely mounted on. an arbor I and in gear with another cog-wheel .1, fast on the main shaft A.

The shaft K carries a lantern-wheel or studplate H, arranged to be engaged from below by a pawl a, which has a fixed pivot 408 and a pressure-sprii'ig 41 also from above by two pawls .TU m, which are curved and pivoted like calipers on a lateral stud cc" of the manipulating-lever .1", fast on a shaft X, which is mounted in fixed bearings. This shaft X carries an arm having two forks w M, which are provided with sticking-pieces screwthreaded for adjustment. The two dogs or pawls x are drawn toward each other by a spring .r". They are arranged and shaped to act on the studs or pins of wheel 11 on opposite sides of the center thereof, the pawl .r by lifting, the pawlv by pushing down, so that their action, though alternate, produces a rotation of the wheel H and windingshaft K always in the same direction, with a step-by-step movement, the pawl :t acting merely as a retaining device.

The main shaft A has a disk J fast on it, the said. disk being provided with two lateral studs andj at unequal distances from its center, which alternately strike the long vertical arm of a bell-crank stop-lever IL, turning on a shaft If, Figs. 4- and 11, and having rigid with it a supplemental arm L, which extends in the reverse direction from the main horizontal arm of the said lever and has two notches in its end for the engagement of a locking s mr L, which serves, by engaging with one or the other of the said notches, to lock the said bell-crank lever in either one of two positions. This spur is on a flexible blade L", fastened to a fixed attachment of the casing, and is pressed. into such engagcment by a spring L, as shown in Fig. .i-.

\Yhen the manipulating-lever a, which extends outward through a slot in the casing, is drawn down by the cashiers hand, it causes the dog to turn the lantern-wheel or studplate ll and the shaft K, thereby winding to some extent the spring of the drum II". The lower fork or tine .r' of the forked arm aforesaid then lifts the horizontal arm of the lever L, thus withdrawing l he vertical arm thereof from the outer stud j" of the disk J and tilting it into position to be struck by the inner stud j when the latter comes around. The spur L at once slips into the upper notch of the arm L, and thus holds the bell-crank lever in this tilted position. The spring-dru 1n and driving-shaft then turn from left to right until the inner stud or stop j comes in contact with the long arm of the bell-crank lever L, that is to say, through somewhat less than a .fourth of a rotation, as shown, when tially the same operation is repeated, except; that the lifting-pawl 12; gives the initial. movement for the winding, and the upper fork or tine a of the forked arm acts on the hori' zontal arm of the bell-crank lever .l. to do press the said horizontal arm and move the vertical arm of the said lever out of contact withv stud j and into the line of revolution of the outer stud j so as to block the latter when a little more than. three-fourths of a revolution brings it around. Thus the downward and upward movements of the manipnlating-lever a; wind and drive the mechanism at suitable intervals, depending on the work to be done, as hereinafter explained. The main shaft A carries also eight cams 1*, i, Q, R, S, T ZY and Z and a worm-wheel Y" for actuating different trains of mechanism.

The cam Q, Fig. 17, is formed with an abrupt shoulder and acts on a bell-crank lever g, which ispivoted at q, provided with a hammer-arm q, carrying a hammer hen the tail of the said lever is left by the cam as the said shoulder passes from under it, a spring connected to the said lever, snaps down the said tail of the lever and strikes the hammer q against a hell f.

The cam R is for the purpose of perioi'lie ally locking the registering-disks 1" before mentioned. To this end it acts on an antifriction-rollor r on an arm "1' of a shaft 13, turning in fixed bearings, 'l ig. Shaft 11 carries also arms r' provided with terminal lateral. spurs r, which are caused by saidv cam to strike against levers r, loose on. the said shaft. These levers r carry trundle rollers 1', each of which is adapted to fit in between two of the teeth a of the disks /l There is an arm. rand a lever r for each disk f. Each lever r is acted on by a spring r, which keeps the trnndleroller r thereof in contact lightly with the said teeth '72. The action of the said cam it, through the above positive devices, is to jam the set of trundle-rollers into the respective series of teethv it, each roller entering between two of the said teeth, and thereby to lock all the disks until the action of the said cam ceases. lly these devices the registering-machiue willv hold the said disks and the indicating-segments connected thereto in the position given them by the rack-bars until it is time to return them to their first position.

The cam T, Fig. 7, is for the purpose of returning the disksfand indicating'segments 7L 7; to their first position. The said cam acts on a trundle-roll carried by an arm C of a shaft C, journaled in fixed bearings. Shaft C carries also a toothed segment 5", gearing with a similar segment '6, loosely mounted on the said shaft g of the regi tering disks and segments. Tl 's segment 6 can ries a lateral arm l provided with four tappets 1', Fig. 8, screwed adjnstably to the said. arm, one for each registering-segment Is, the

such rotation is checked again by the said said tappets being respectively arranged to stud. W hen the lever fr lS raised, substanstrike the supporting-arms of the said segments and return the latter to their first position under the impulse of the said cam T By reason of the connections made by rods or bars 1 the same operation returns the disks f and segments it simultaneously and in like manner to their first position. The registering mechanism is then all ready to register another payment. The roll remains in its raised position until lowered by the action of the corresponding rack on the wheel fmeshin g therewith in indicating a payment. Thus through the medium of its corresponding segment 7c, arm t and segments 21 t arm G will restore said roll into position to be lifted by the cam T again. If the payment is not such as to require the registering operation of this particular disk and segment, of course the said roll will remain unaffected by the rotation of cam T during the replacing operation, and will be aboveand out of reach of the said cam.

The cam Y Figs. 3 and 10, acts on a trundle-roller on one arm of alever o, and thereby shifts a shutter which is carried by the other arm of said lever, away from the win dow j on the customers side to open the same, but allows it to fall into its closing position when there is no longer need to inspect the figures on the disks through the said window.

The cam S acts 011 a trundle-roller s on an arm 5 of a small shaft 8 which shaft carries also arms 5, equal in number to the registering-segments 7c and arranged for contact, respectively, with the lower spokes of the said segments. These arms 5 are short and merely serve to replace any one of the said segments and the connected disk f in accurate position in case by reason of some slip of the teeth of the disk and rack the said segment and disk have accidentally moved too far.

The worm-wheel V gears with a worm V fast on a shaft V, turning in fixed bearings, and thereby-keeps a wing-regulator V, also fast on said shaft, continuously in rotary motion whenever the driving-shaft rotates.

The cam P is for the purpose of throwing the series of pinions 0, before referred to, into and out of gearwith the teeth n of registering-disks f. To this end the said cam acts on an arm P, Fig. 13, of a rock-shaft P, which is provided with radial arms 19, serving as supports for a bar 19, on which bearing-blocks are formed in pairs for the short shafts or axial rods 0 of the said pinions 0, one small shaft to each pinion. A spring P holds the arm P in contact with the cam P and also operates, when the said cam passes from under it, to turn back the said rock-shaft and replace the bar 1) and devices carried thereby in their first position. By the alternate action of the said cam and the said spring the said pinions are moved collectively first into one and then into the other of their extreme positions of oscillation. In one of these positions they gear with the teeth n of the disks f. In the other they gear with a series of stud wheels or lantern wheels i, turning with short shafts i one shaft to each wheel 25, jonrnaled in fixed bearing-blocks 79, arranged in pairs. Only the first pinion 0, which gears when in one position with the disk f, representing the denominational units of currency, such as cents or centimes, does not gear with any wheel 25 when in its other position. There is also a pinion o in 0011- tinuation of the series 0 at the other end of the said series, which gears with the last of the lantern-wheels i when shifted into one position of vibration, but does not gear with any disk f when in the other position. Thus the series of pinions exceed by one the series of disks f and the series of wheels 15; but as considered with regard to these two series the inactive pinion in the one case is at the opposite end of the series from the inactive pinion on the other.

Each pinion o is integral with a cam s and a sprin g-drn 1n n, the latter being provided with an external ratchet-wheel to, Figs. 2, 18, and 20. The inclosed coiled spring a of each drum u is attached at the outer end to the said drum and at the inner end to a sleeve or hub 0 loose on the said fixed rod or shaft 0 and extending within the said drum, as shown in Fig. 20. This sleeve or hub carries a disk or plate .2 which closes the end of the said drum, also a toothed segment O beyond the said disk. The disk or plate extends at one point beyond the periphery of the said drum and is there provided with two lateral studs or rods 10 w, extending laterally across the front of the said drum, but at different distances from the center of the said disk. The latter is also provided on the other side and at the opposite point of its diameter with a lug or contact-piece .2, Figs. 13, 15, and 20. The peripheries of the drums u are graduated to correspond to the segments h and 7c. The ratchet-wheels u are respectively engaged by retaining-pawls y, fastened on blocks 3 of bar 1). The construction of each group of de vices accompanying each wheel 0 on its rod or shaft 0 is the same; but the drum n, integral with supplemental pinion 0', has no spring, and there is no cam s on its shaft 0.

The blocks y aforesaid are provided with pivot-pins 3 one to each, for the bent arms Y, each of which has a lateral projection g Figs. 19 and 20. Helical springs f on the aforesaid pivot-pins 1 hold the arms Y respectively against the cams s, which are integral with the pinions 0. Each arm or lever Y is normally in position to lock the disk or plate 2 and segment 0 by the contact of its projection y with the inner stud w of the said disk.

\Vhen any rack in the act of registering a payment is caused to turn its registering-disk f, the eam s on the same shaft with the latter is turned thereby to the same extent. This cam bears against the corresponding lever Y and presses the-latter outward, so as to remove the projection y" of this lever from the path of the inner stud it, or, if the payment and consequent movement of the rack-regis tering disk and cam s be great enough, out of the paths of the stud u and the stud u" as well. This latter result will be attained whenever the aggregate movement of the disk f in registering successive payments will turn the eam .9 far enough to make it move the cam Y and projection 11/ into position to avoid both of the said studs. If the movement of the said cam is only sufficient to move the projection 3 beyond the inner stud it, the latter is freed and the disk turns through a small part of its rotation, being stopped at the end of it by the contact of projection y" with the outer stud 1r. \Vhen the movement of the disk f, in again registering payment, so far turns the cam s that the projection 1 is removed from contact with stud tr, as above stated, the disk .2 is freed again and turns through the remainder of its rotation, being stopped at the end thereof by the contact of its lug .2" with lever .2

The lug or contact-piece .2" of each disk is arranged to be locked by the corresponding arm .2 of a series thus marked, the same be ing fast on a shaft 2', Figs. 13 and 1-5, which is journaled in fixed bearings and provided with two additional arms .2" and .2". The arm .2" has a spring attached to it for holding the said arms .2 against the contact-pieces or lugs .2" or drawing them into position for such contact. The arm .2 carries an antifrictionroller .2 which runs on a cam Z of the main shaft A and is actuated by the said cam to remove the arms from such contact with lugs .2" and leave the said disks .2 free.

Each lantern-wheel or stud-wheel t has a gearavheel. t integral or rigid therewith and turning on the same axis. The periphery of each wheel '6 is provided with fifteen teeth, divided into groups of three teeth each, every such group being adapted to gear with one of the toothed segments 0 when the rockshaft l? is turned, so as to shift the bar 19 and series of rods or fixed shafts O to one of the two positions which are alternately occupied by the bar 1) and shafts O, collectively considered. The spring it of each drum u, integral with gear-wheelu, is attached at its inner end to the hub or sleeve 0' and at its outer end to the said drum. Each oscillation of the said segments 0 on their shafts O under the stress of the springs of drums a, when the disks .2 are freed from the locking-arms Y and .2 causes the corresponding gear-wheels L and lantennwheels i. to make one-Jifth of a rotation. Each lantern-wheel t is in gear with the pinion 0 one decimal place ahead of the segment 0 which turns said wheel. During one part of the operation of the mechanism the said stud-wheels or lantern-wheels i are I locked by flat springs 7?, Figs. 13 and 16, which triuidle-roller if to move the said s n-lugs in to such contact. Normally they do not press on the said lantern-wheels.

In describing the various parts of my machine the operation of nearly everything except the carrying mechanism has been snlih ciently explained, but for the sake of greatm' clearness I will now set forth the entire operation in due order.

The cashier after each payment has three distinct manipulations to perform. :hirst, he slides the keys I) along their slots to exhibit. the amount of the payment through the windows t' j, as described. Secondly, he dop resscs the 111E111lPUlZILlIlQ-TQYOI':17, winding the n'iainspring to some extent, partly for the pn rpose of locking the registering disks and sew ments in the position given them by the sliding of the said keys. This locking is effected by the rotation of the main shaft and cam ill under the impulse of the said spring and the consequent operation of arm 1-, shaft l arms r and lovers 1', whereby the rollers r are forced into locking engagement with the tee! h n, as before described. Thi rdly, he raises the manipulating-lever a: and thereby winds the said mainsp ring still more, its expansimi then serving to replace the said registering devices in their former position ready for another act of registry to ring the bell and move the shut for over the window.

It is unnecessary to repeat the action of the pawls 5t" and at, lantern-wheel If, the he ver ll, spur l), the forked arm, disk .1, mainspring-drum ll, and connectinggears for driving the main shaft. The deprer-ssion of the said manipulating-lever puts the spring of said drum under all. the tension that is necessary to drive the mechanism until the stud j stops it by contact with the vertical arm of lever L. The cam ll causes the arm '1" to press the springs l" on the wheels and hold them motionless. The earn 1 rocks the shaftthrough arm 1 so as to shift the pinions o from the laiiitern-wheels 1? into gear with the teeth 76 of the disks f. The *am it rocks the shaft .8, as aforesaid, and by means of the described intervening devices forces the rollers 1' into engagement with the teeth a of diskf, so as to lock the registering mechanism in the position given it by the keys and rack-lmrs. The cam Y simultaneously removes the shutter u from the window During the above operations, caused by the depression. of the actuating-lever and the consequent rotation of cams F, W, R, and Y, the cams (g, S, T, and Z turn without producing any effect.

The winged regulator V at all times keeps the action of the mechanism even and regular.

When the cashier raises the manipulzuinglever .r from the lowest to the highest point, the forked arm moves the lever L to free the disk J, which is caused by the springdrum 11 to turn until the other stud of the said disk comes in contact with :the said lever, that is to say, through the greater part of a complete rotation. The said. lever is provided with a IIC lug for such contact, as indicated by dotted lines. The cam F, turning with the shaft A, again holds the lantern-wheel t motionless. The cam Q begins to raise the bell-hammer for action. The cam T returns the registering mechanism, as before described, to its first position, the cam R simultaneously releasing the disks f by ceasing to act on. the roller carried by arm r, thereby allowing the rollers r to fall out of locking engagement with the teeth n of the said disks. The rotation of said disks has already turned correspondingly the respective pinions 0, these being equal thereto in the number (ten) of their teeth, and of course thereby has turned also the graduated drums it each to the same extent as its pinion. The returning action of cam T and the devices actuated thereby of course affects only the registering-disks f and segments h and 7t. The pinions 0 and drums u retain the positions to which they have been turned, so that successive payments may be added to the amount indicated already on the said drums, as hereinafter explained.

During the rotation of each pinion 0 and its drum n by the corresponding toothed disk f the spring a is wound thereby and would turn the disk 2' and three-toothed segment 0, which are on the same shaft with the said pinion and drum, but for the locking of the said segment by the lever Y, as explained. hen the cam s, acting on said lever Y, disengages its lateral projection if from the inner stud w of the said disk 2', the latter will turn under the impulse of the said spring until stopped by the contact of the said projection with the outer stud w of the said disk 1f the said cam s has been turned far enough'to make the said projection avoid the inner stud w, as well as the outer one to, the disk .2 will turn until it makes a complete rotation, when it is stopped by the contact of arm .2 with lug .2". \Vhether the disk z will turn through the distance corresponding to the interval between studs in and w, as first above described, or through a complete rotation until stopped by arm 2 will depend in any particular opera-- tion on the total of the sums added on the said drum. If this be great enough to call for carryin g to the next decimal place, the entire rotation will be made. The effect of this is to put thethree-toothed segment O,which turns with the disk 5, in position to engage one of the five sets of three teeth of the wheel t, which turns the five-stud lantern-wheel t, meshing with the pinion o of the next higher decimal place. The cam P then releases the rock-shaft P, and the counteracting spring acts on the latter to shift the pinions 0 (except the first one) into gear with the lantern-wheels 0, respectively. During this movement the said pinions and their drums are held from turning back under the expansive action of springs a only by the engagement of the ratchets u with the retaining-pawls. Simultaneously with this shifting the cam P arm T, and intervening devices release the lantern-wheel t and the wheel 25, carrying the five series of three teeth each. The cam Z then withdraws the arms 2 from position for contact with the lugs z of said disks ,2, leaving all ofsaid disks free to turn under the impulse of springs 21 except those disks which, as aforesaid, have not yet been released by the levers Y- that is, the disks z (and those only) are free to turn farther which are needed to take part in the arithmetical operation of carrying; but they cannot turn beyond a single complete rotation, for the arms are again interposed by the action of cam Z, a little before such rotation is ended, in position for contact with said lugs z and to lock the said disks. The first pinion 0 is not in engagement with any wheel t, because there is never any need to carry in the units place. The last pinion 0 has no spring nor disk .2, because there is no indicating device to which 1 maybe carried therefrom. If five cents be first received, the first key and rack are moved far enough to turn the disk f which is first in series through a distance of five teeth, exhibiting the numeral 5 on the segments hand it and the drum to belonging to the units place. The shafts O are then vibrated from one position to the other without effect, the registering mechanism being meanwhile returned to its former position ready for another act of registry, but without affecting the position or indications of the totalizing devices 0 and it. If new another payment of three cents be made, the operation, pro tcmto, will be repeated, and after the registering-disks f and segments 7t and 7c are replaced in their first positions the numeral 8 will be presented by the units-indicators 72., 7c, and it. If the next payment be four, making a total of twelve cents, the units-pinion 0 and drum to will turn through four places, exhibiting the numeral 2 and leaving 1 to carry to the tens place. This carrying is automatically effected as follows:- The three-toothed segment 0, which is connected through its hub to the spring'u of the said drum, being in engagement with one of the sets of teeth of the wheel t, and the corresponding disk 2 being forced from the levers Y and 2 as aforesaid, the spring a of the said drum gives a complete rotation to said disk and said segment, thereby turning the wheels 25 and t through one-fifth of a rotation, which is transmitted as a one-tenth movement by one of the studs or rods of the said wheel t to the pinion 0 of the tens place, turning it forward one tooth and presenting the numeral 1 of the corresponding drum 1b. This, with the two exhibited by the units-wheel, will make up the twelve required.

The carrying from tens to hundreds and so on through all the decimal series will be done in the same way. Of course large sums may be added as well as small ones, but for convenience and conciseness of explanation a simple instance of small successive payments has been chosen.

After each payment is registered the hammer strikes the bell and, with short interval for inspection, the shutter covers window j.

liaving thus described my invention, what 1 claim as new, and desire to secure by 'lfletters Patent, is-
